Out now - All The Borders - 1936 edition: https://umap.openstreetmap.fr/en/map/all-the-borders-1936-edition_1276889

A fan remix of @jon's map, reflecting the situation before WW2 as best as I could determine.
It turns out having lots of old borders that don't sit on modern border is pretty much a Polish thing, who would've thought?
